The invention relates to the technical field of laser welding, in particular to a laser output system and a welding method for simultaneously welding multiple intensive points. The laser output systemcomprises multiple light paths arranged in parallel, wherein each light path comprises a laser light source, a transmission fiber, a cylindrical mirror group and a wedge-shaped mirror; the multiple paralleled light paths form a convergence light path after passing through the wedge-shaped mirrors; each cylindrical mirror group comprises a Y-directional cylindrical mirror group and an X-directional cylindrical mirror group; each Y-directional cylindrical mirror group comprises a Y-directional plano-convex cylindrical mirror and a Y-directional plano-concave cylindrical mirror; each X-directional cylindrical mirror group comprises an X-directional plano-convex cylindrical mirror and an X-directional plano-concave cylindrical mirror; each cylindrical mirror group adjusts a laser beam in an Xdirection and a Y directi
